Reference is had to the accompan ing drawings which illustrate thepreferred orm of the invention, though it is to be understood that theinvention is not limited to the exact details of construction shown anddescribed, as it is obvious that Various modifications thereof withinthe scope of the claims will occur to persons skilled in the art.

In said drawings:

Fig. 1 is a sideelevation, partly broken away, of a mine car constructedin accordance with this invention; l

Fig. 2 is a-top plan view of shown in Fig. l; r

Fig. 3 is a transverse section taken on the line 33 of Fig. 2; and

Fig. 4 is a partial transverse section of a mine car of modifiedconstruction.

It is an object of this invention to provide a mine car of improvedconstruction having journal boxes directly supporting portions of thefloor. It is also an object of this invent on to provide an improvedmeans for bracing the sills of a mine car in which the axles passthrough the sills and it is also an object of this invention to providean improved means for bracing the floor of a mine car of the type inwhich portions of the floor are on different levels.

With these and other objects in View, a

\J the mine car invention, comprises as shown in the drawings, sills 1of Z-shape extending from end to end of the car and having their webs 2placed vertically and the flanges placed horizontally, the top flanges 3pro ecting outwardly and the bottom flanges 4 pro ectmg inwardly andbeing of greater w1dth than the top flanges 3. The bottom flanges 4 arejoined by a plate 5 secured to the flanges 4 by rivets 6 and forming thecenter floor portion of the car. The plate 5 ends short of the webs 2 ofthe sills 1 so that when the plate 5 v is moved transversely of the carinto contact with the web 2 of one of the sills l the opposite edge ofthe plate 5 will be free of the sills 1 are connected by a tie 26 formedof flange 4 of the other sill 1 and may be moved past the outer edge ofthe fiange thus permitting of the insertion and removal of the plate 5in either assemblage or replacement.

1925. Serial No. 32,094.

To the webs 2 of the sills l journal boxes 7 are secured by bolts 8which engage in openings in the webs 2 of the sills 1 and flanges 9 ofthe journal boxes 7 which contact with the webs 2. Flanges 10 of thejournal boxes 7 bear against the bottom surfaces of the top flanges 3 ofthe sills 1.

To the top flanges 3 of the sills 1, of the construction shown in Figs.1 to 3, are secured horizontal outwardly projecting plates 11 formingtheside floor portions of the car and restingupon the journal boxes 7.The plates 11 have formed integral therewith upwardly bent portionsforming the sides 12 of the car. The car sides 12 are finished withrolled-over portions forming reinforced upper edges 13 for the sides.

The plates 11 are provided with openings 14 whichreceive the upperportions of wheels 15 carried by axles 16 which are mounted in plate 5forming the center \portion of the v car floor. The openings '14 arecovered by wheel hoods 17 secured to the plates 11 by rivets18, theheads of the rivets adjacent the journal boxes 7 being received inrecesses formed in the journal boxes. I

The portions of the axles 16 between the sills 1 are coveredby axlehousings 19 of substantially an inverted U-shape with outwardlyprojecting flanges 20 secured to the plate 5 by rivets 21 and adjacentrivets 6. Toward the ends, the housings 19 decrease in width andincrease in height and at the ends areformed with outwardly projectingvertical flanges 22 secured to the Webs of the sills by rivets 23 andwith outwardly projecting horizontal flanges 24 which overlap the plates11 and .top flanges 3 of the sills 1 and are secured thereto by therivets 25 which secure the plates 11 and top flanges 3 together at thatpoint, the head-s of the rivets 25 fitting into recesses formed in thejournal boxes 7.

At the center of the car the webs 2 of the of the sills 1 by rivets 32.Angle braces 33' riveted to the sill webs 2 and the vertical flangesills 1.

To aid in supporting the load on the side floor portions braces areprovided which are bent to conform to' the shape of the plates 29 aidin'securing the tie 26 to the 11 and are riveted to the car sides 12 andthe side floor portions and extend at an angle from about thelongitudinal axis of the side floor portions toward the bottoms of thewebs 2 of the sills 1 and are then bent u wardly, contacting with theouter faces 0 the sill webs 2 and being riveted to the webs. The braces35 are placed at the car ends, at the center tie 26 and adjacent theaxle housings 19 so that any tendency of the braces 35 to twist thesills 1 will be resisted by the car ends, the center tie26 and the axlehousings 19 which serve to secure the sills in relatively fixedpositions.

It will be noted that in a car constructed in accordance with thisinvention the plate 5 forming the centerportion of the floor may beremoved for repairs or replaced by removing the rivets securing theplate 5 to the sills 1, axle housings 19 andties 26; that the sideportions of the floor are adequately braced by the braces 35 secured tothe sills 1; and that any tendency of the braces 35 to distort the carwill be overcome by the manner in which the sills are connectedtogether. It will also be noted that the axle housings 19 and tie 26will serve as compression members and prevent distortion of the car bodyby the load on the center portion of the car.

In the modified construction shown in Fig. 4 the plates 40 forming theside floor portions incline upwardly from the sills 1 and the topflanges 3 ofthe sills 1 are bent to conform to the inclination of theplates 40. In this construction, the braces 41 are in contact with andfastened to the plates 40 forming the a car sides 42 and side floorportions from the upper edges of the car sides 42 substantially to thesills 1 and are then bent downwardly to engage the outer faces of thesill webs 2 substantially to the bottom flanges 4 of the sills 1 and arethen bent outwardly and upwardly into contact with the portions of thebraces 41 secured to the side floor portions at substantially thelongitudinal axes of the side floor portions, both portions of thebraces 41 being secured to the plates 40 by the same rivets 43.
